You could get the coordinates of every pixel and check if the mouse is inside of it But I'm guessing there is a far easier way.

Maybe have an invisible sprite at the mouses position, and check if the invisible sprite is colliding with your sprite?

i have an invisible sprite at the mouse's tip.

but knowing where a sprite is doesn't help in the clicking part. i mean, is there a command that would help me know if a sprite was clicked on?

you check if there is a collision between the invisible sprite and your organic sprite... I don't seem to understand? I don't do a lot with 2D, so is the collision ignore transparent parts of the sprite or not?

You need to simply place a 1x1 invisble sprite at the mouse coordinates each loop and check for a collision. There is plenty of pixel perfect collision code on this board, a quick search should find several functions.
